General Comments. ( Brief data summary and scan listing )
N15Q1 had 7 stations (+ VDIF data from Ef and O6 that are listed as Ex and Ox, respectively), 8 x 16 MHz IFs, 4 polarizations, and used 64 frequency points per IF/pol, with 1s integrations. The SOLINT was set at 1.0 min. Ef was used as the reference station. The fringe-finder and bandpass calibrator were '2007+777', '3C345', and 'DA193'. The continuum target source 'J2022+7611'was calibrated using the phase-reference sources '2007+777'.

The EVN reliability indicator (ERI) for this experiment was ERI = 0.89 . ERI* = 0.99 . (EF=1/1, ON=1/1, YS=0.97/0.97, MH=1/1, KU=1/1, KY=1/1, KT=0.66/1)

Plots of the autocorrelations
Comments.
Each scan plotted separately, all stations.

plots of the uncalibrated amplitude and phase against time
Comments.
Full-experiment for Ef-* baselines, no calibration applied.

Plots of the uncalibrated amplitude and phase against frequency channel
Comments.
Scalar averaged Ef-* baselines, each scan plotted separately. No calibration applied yet.

The uncalibrated amplitude and phase of the crosshand correlations against frequency channel
Comments.
Scalar averaged Ef-* baselines for LR, each scan plotted separately. No calibration applied yet.

TSYS against time
Comments.
TY1 table, each IF/pol on a separate plot. For KVN antennas we used nominal TSYS.

Telescope sensitivities from the a priori TSYS and Gain curves (the square of this number gives the antenna noise (SEFD) in Jy - the smaller the better).
Comments.
Gain amplitude from CL2 table.

Fringe-fit phase solutions (including Parallactic Angle correction).
Comments.
CL3 station phase solutions -- CL3 = CL2+SN2, thus also includes the initial amplitude/parallactic angle calibration from CL2 and the fringe solutions from SN2.

Fringe-fit delay solutions
Comments.
SN2 station delay solutions for the fringed sources, each IF/pol on a separate plot.

Fringe-fit rate solutions
Comments.
SN2 station rate solutions.

Telescope bandpasses
Comments.
Bandpass table 1. 2007+777, 3C345, and DA193 were used for bandpass calibration.

Calibrated amplitude and phase against time (a priori amplitude calibration and fringe-fit solutions applied).
Comments.
Full-experiment for Ef-* baselines, calibrated with CL3.

Calibrated amplitude and phase against frequency channel
Comments.
Ef-* baselines calibrated with CL3 and BP1. The amp and phaseplots self-scale, not necessarily going down to 0 in the case of the amps.
